Paul Bunyan's Woodpile

A geological curiosity--rare in Utah--the "woodpile" is a cluster of lava logs formed about 30-million years ago during the Eocine period. The logs were formed when a lava flow cooled into orderly columner joints having 3 to 6 sides. The column measures about a foot in diamater and up to 15-feet in length. This formation was on the rim of a caldera that collapsed due to a voild left when lava flowed out from under the caldera. Basin and range faulting caused the formation to tilt onto its side.
